Well, I thought Arduino would send me a notification when someone would responds but apparently not.. I'm sorry for the time i took to respond I was terribly busy..
So here is the link for ILCD website : Intelligent Products for Smart Solutions - demmel products gmbh
I'm using the evaluation kit.
Unfortunately it seems like the screen isn't used a lot so finding documentation on this product is pretty hard..
Hope someone will know how to program the screen with arduino.
